Abstract Today, the manufacturing industry must adapt to dynamic customer needs, changing from time to time following market trends. So that the production process in manufacturing requires adjustments, one of which is by forming social manufacturing. This study aims to create an integrated production system model based on social manufacturing, which involves several Socialized Manufacturing Resources (SMR) as manufacturing resources that are socialized to produce a product. The methods used are field observation, literature study, design of a social manufacturing-based production system model, model simulation using ProModel software, and analysis of model simulation results. In this study, the simulation involves four SMRs, each of which makes a part that has been given specifications by the manufacturer based on customer requests. The product produced is the Sanitation Chamber, which is equipped with a control system to monitor reading data via the internet. The model simulation uses the Pro Model software and analyzes resource use, location utilization, and resource costs.

Abstract The article describes a student capstone design project completed by a team of five students and implemented by a resort and casino in Northeastern Pennsylvania (NEPA). This project was completed within the framework of project-based learning (PBL). Students had the opportunity to apply the knowledge that they learned in the classroom in a real-world application. Students also had the opportunity to work as a team which was supervised by the faculty. The outcome of the project provided valuable experience in creating of grid, a reliable source of energy. The heat generated as a by-product was used for the purpose of heating hot water and a swimming pool as well as space heating for the hotel and casino during the winter. In the summertime the excessive amount of heat was used to dehumidify the air in the hotel and casino. Dehumidifying the air increased the level of comfort in the hotel and casino as well as in the enclosed swimming pools area. The article is focusing on the cost effectiveness of the off-grid heat-and-power solution. The net present value and internal rate of return as well as the payback time were calculated.

Abstract The purpose of this article is to introduce some of the problems arising from the rapid development and raising the status of machines and the increasing disregard for human rights in the context of the use of cognitive technologies. Cognitive technologies are highly acclaimed and are being introduced into almost all aspects of life, especially in business. The article asks the question of whether the use of these technologies leads to a gradual humanization of machines while dehumanizing humans. The article is purely theoretical and based on a literature study of selected bibliographic items. On the basis of the analyzed texts an attempt was made to introduce the concept of artificial intelligence, cognitive technologies and algorithms. It also attempts to diagnose the state of work on the regulation of the legal situation related to the development of artificial intelligence and cognitive technologies, as well as the status of robots. The philosophical concept of dehumanization and its selected examples are also outlined. The discussion leads to the conclusion that the pace of development of cognitive technologies, overtaking the human ability to comprehend them, poses a threat of machines getting out of human control.

Abstract The imbalance in bike-sharing systems between supply and demand is significant. Therefore, these systems need to relocate bikes to meet customer needs. The objective of this research is to increase the efficiency of bike-sharing systems regarding rebalancing problems. The prediction of the demand for bike sharing can enhance the efficiency of a bike-sharing system for the operation process of rebalancing in terms of the information used in planning by proposing an evaluation of algorithms for forecasting the demand for bikes in a bike-sharing network. The historical, weather and holiday data from three distinct databases are used in the dataset and three fundamental prediction models are adopted and compared. In addition, statistical approaches are included for selecting variables that improve the accuracy of the model. This work proposes the accuracy of different models of artificial intelligence techniques to predict the demand for bike sharing. The results of this research will assist the operators of bike-sharing companies in determining data concerning the demand for bike sharing to plan for the future. Thus, these data can contribute to creating appropriate plans for managing the rebalancing process.

Abstract COVID-19, mobility, socio-social changes have transferred to the world of social media communication, purchasing activities, the use of services. Corporate social media has been created to support clients in using various services, give them the possibility of easy communication without time and local barriers. Unfortunately, they still very rarely take into account the security and privacy of customers. Considering that the purpose of this article is to investigate the impact of social media on the company’s image, it should be remembered that this image also works for the security and privacy of customer data. Data leaks or their sale are not welcomed by customers. The results of empirical research show that the safety, simplicity and variety of services offered on social media have a significant impact on the perceived quality, which in turn positively affects the reputation. The authors proposed a methodology based on the Kano model and customer satisfaction in order to examine the declared needs and undefined desires and divide them into different groups with different impacts on consumer satisfaction. The interview participants were employees of 10 randomly selected companies using social media to conduct sales or service activities. 5,000 people from Poland, Portugal and Germany participated in the study. 4,894 correctly completed questionnaires were received.

Abstract The automotive industry is one of the fastest growing sectors and therefore places demand on many other sectors and increases the need for cooperation. With the development of the automotive industry, tires have become an integral part of society and the everyday life of the individual. As a result of the company’s development as a connection of transport, the demand for tires is increasing and the production of waste tires is also related to this. The use of end-of-life tires is almost endless and that is why tires are good to use in the circular economy. The circular economy is an economic system that aims to keep products and materials in use for longer, thus increasing their productivity and reducing waste. The paper presents a methodical concept of the plan for the extension of production capacities of rubber-based pressed products with the intention to produce noise reduction panels. The investment consists of the acquisition of the pressing machine and respective mould in the amount of € 180,000. Based on the selected assessment methods it can be stated that the NPV reaches + 69,360 €, Profitability index is 1.38, Internal Rate of Return is 23.8% and the payback period is estimated for 4 years and 4 months, at the considered production capacity of 14,000 m2/year.
摘要汽车行业是增长最快的行业之一,因此对许多其他行业提出了需求,并增加了合作的需求。随着汽车工业的发展,轮胎已经成为社会和个人日常生活中不可或缺的一部分。由于该公司的发展与交通运输相连,对轮胎的需求不断增加,废旧轮胎的生产也与此有关。报废轮胎的使用几乎是无休止的,这就是为什么轮胎在循环经济中很好使用的原因。循环经济是一种旨在使产品和材料使用更长时间,从而提高生产力和减少浪费的经济体系。本文提出了一个系统的概念,旨在扩大橡胶基压制产品的生产能力,以生产降噪板。投资包括收购压机和相应的模具,金额为180000欧元。根据所选的评估方法,可以说净现值达到+69360欧元,盈利能力指数为1.38,内部收益率为23.8%,投资回收期预计为4年零4个月,考虑的生产能力为14000平方米/年。

Abstract Surveys performed among the residents of Zabrze indicate that in 2021 the majority of respondents (67%), wishing to use public services provided by the local government, still preferred to visit the office in person. Residents noticed negative aspects of direct service, such as queues of people waiting for the case to be completed (26%), excessive bureaucracy (24%) or lack of parking spaces (18%). However, they counted on help in completing the necessary formalities by officials who should be: professional (20%), communicative (18%) and kind (17%). The use of the digital platform (ePUAP) dedicated to customer service was reported by 32% of respondents. At the same time, as much as 40% of the respondents, in order to save time and to simplify procedures, declared their will to use innovative methods of remote contact with public administration (e.g. via social media). The COVID-19 pandemic showed that it was possible to increase (even by 250%) the number of cases handled remotely, which with over 90% of households in Poland with access to a computer network creates opportunities for integrated development as part of the Smart City idea. The aim of the paper was to identify the residents’ expectations related to the provision of public services by local administration. Precise determination of the ways of perception of both direct and remote customer service has not only an application value. It also allows for further research study on the management of local government, including the organization of management control, as well as social communication of local governments.
摘要对Zabrze居民进行的调查表明,2021年,希望使用当地政府提供的公共服务的大多数受访者(67%)仍然更喜欢亲自去办公室。居民们注意到了直接服务的负面影响,如排队等待案件完成(26%)、过度官僚作风(24%)或缺乏停车位(18%)。然而,他们指望那些应该专业(20%)、善于沟通(18%)和善良(17%)的官员帮助他们完成必要的手续。32%的受访者表示使用了专门用于客户服务的数字平台(ePUAP)。与此同时,为了节省时间和简化程序,多达40%的受访者表示,他们愿意使用创新的方法与公共行政部门进行远程联系(例如通过社交媒体)。新冠肺炎疫情表明,远程处理的病例数量有可能增加(甚至增加250%),波兰90%以上的家庭都可以使用计算机网络,这为作为智能城市理念一部分的综合发展创造了机会。该文件的目的是确定居民对地方行政部门提供公共服务的期望。准确确定直接和远程客户服务的感知方式不仅具有应用价值。它还允许对地方政府的管理进行进一步的研究,包括管理控制的组织,以及地方政府的社会沟通。

Abstract Poland is a participant to the European Union Emissions Trading System, which aims at reducing greenhouse gas emissions. Trading CO2 emission rights has become a strategic area from the point of view of managing entities that emit CO2. The aim of the paper is to investigate and identify discrepancies in the presentation and valuation of CO2 emission allowances, CO2 emission provision liabilities in reporting, and to assess the impact of these discrepancies on compliance with the true and fair view principle on top of the informative value of the financial statements. An in-depth qualitative analysis was used to examine disclosures of CO2 emission rights in the 2020 consolidated financial statements coming from the largest energy sector groups listed in the WIG Energy Index of the Warsaw Stock Exchange in light of the relevant legal acts and literature. As a result of the research conducted, it was confirmed that groups of companies carry out a range of CO2 emission rights balance classification and valuation. There were also significant discrepancies in the disclosure of information about the creation and valuation of provisions for liabilities due to CO2 emissions. The discrepancies observed in the audited entities’ balance-sheet presentations and valuation of the acquired CO2 emission allowances and reserves resulting from IAS/IFRS in practice distorts the comparability of data presented in the financial statements. The research also revealed differences in scope of disclosed information, as well as its fragmentary nature. As a result, the comparison of data between groups in the energy sector in terms of their assets is impossible. Our study fills a research gap on the effects of using IFRS for the presentation and valuation of CO2 emission rights in the Polish energy sector and the impact of a differentiated approach to disclosures on the true and fair view conception in financial reporting.
波兰是旨在减少温室气体排放的欧盟排放交易体系的参与者。从二氧化碳排放主体管理的角度看,二氧化碳排放权交易已成为一个战略领域。本文的目的是调查和识别报告中二氧化碳排放限额和二氧化碳排放准备负债的列报和估值差异,并评估这些差异对财务报表信息价值之上的真实和公允观点原则的遵守的影响。根据相关法律行为和文献,对华沙证券交易所WIG能源指数中最大的能源部门集团在2020年合并财务报表中披露的二氧化碳排放权进行了深入的定性分析。研究结果证实,企业集团开展了一系列的二氧化碳排放权平衡分类和评估。在公布关于二氧化碳排放造成的负债的规定和估值的资料方面也存在重大差异。被审计实体的资产负债表列报和根据国际会计准则/国际财务报告准则对获得的二氧化碳排放限额和储备的估值存在差异,这在实践中扭曲了财务报表中数据的可比性。该研究还揭示了披露信息范围的差异,以及信息的碎片性。因此,不可能对能源行业各集团之间的资产数据进行比较。我们的研究填补了关于使用国际财务报告准则对波兰能源部门二氧化碳排放权的列报和估值的影响以及差异化披露方法对财务报告中真实和公平观点概念的影响的研究空白。
